85k miles on Tahoe.
While driving, the engine light came on and the dash displayed a warning " Reduced Engine Power" which reduced my engine speed to a maximum of about 20 mph. I replaced the TPS after the first time it happened and thought it the problem was fixed. After 2 weeks of problem free driving, it happened again. When this happens, if we let the vehicle sit for a while, it will run well enough to get it home. I'm at a loss, and need advice.
thanks
